kiwi-racer Posted January 3 Report Share Posted January 3 Hi, with my sexy new G5, LS3 Engine, we wired up dual connections 4.9 on Plug E for the Bosch 4.9 Wideband Sensors, Can I use the AEM X Series Calibration, as I believe they all use that Sensor ?, or is that scaled differently as the signal comes from the AEM box ? Here's the cross reference on who uses these sensors Bosch Part Number: 0 258 017 025 ( 0258017025 ) Bosch USA Part Number: 17025 AEM Part Number: 30-2004 AiM Part Number: X05LSU490 AiM Part Number: MC-330 MSD part number MSD 2267 for POWER GRID WIDEBAND MODULE 7765 thanks !

dx4picco Posted January 3 Report Share Posted January 3 are the widebands sensors connected directly to the ECU, or through AEM controler? if to the ECU then there shouldn't be anything related to AEM scaling? Quote Link to comment Share on other sites More sharing options...
kiwi-racer Posted January 3 Author Report Share Posted January 3 They are directly connected to the ECU no 3rd party wideband controller. But I need calibration that maps the voltages to the values. Quote Link to comment Share on other sites More sharing options...
Confused Posted January 3 Report Share Posted January 3 No, you don't. The ECU talks directly to the sensors, and does everything you need it to. If you think you need to set a calibration, you've set something up incorrectly, and haven't followed the instructions/Help. In the configuration tree, you do go to Analog Inputs -> Lambda 1/2, but from the "Lambda Sensor Control" option you simply choose "Internal", and that's it, everything done.
